In Hindu tradition, Sunday is dedicated to Lord Surya, the Sun God, with worship believed to bring health, success, and protection. The Raviwar Pujan Vidhi involves offering water to the rising sun while chanting mantras. Worshipping Lord Vishnu, Goddess Durga, and Lord Bhairav on this day is also considered auspicious, aiming to remove obstacles, negativity, and ensure divine protection and emotional balance.
